<p>After reviving many bug reports, we recognized some of them spot
unexpected EOF. The chop target was developed based on this recognition.</p>
<p>The chop target generates many input files from an existing input file
under <em>Units</em> by truncating the existing input file at variety file
positions.</p>
<div class="highlight-default"><div class="highlight"><pre><span></span>$ make chop  LANGUAGES=LANG1[,LANG2,...]
</pre></div>
</div>
<p>It takes a long time, especially with <code class="docutils literal"><span class="pre">VG=1</span></code>, so this cannot be run
under Travis CI. However, it is a good idea to run it locally.</p>
<p>slap target is derived from chop target. While chop target truncates
the existing input files from tail, the slap target does the same
from head.</p>
